Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147466644, here are decompositions:

  • 3 + 2147466641 = 2147466644
  • 97 + 2147466547 = 2147466644
  • 157 + 2147466487 = 2147466644
  • 181 + 2147466463 = 2147466644
  • 307 + 2147466337 = 2147466644
  • 331 + 2147466313 = 2147466644
  • 457 + 2147466187 = 2147466644
  • 523 + 2147466121 = 2147466644

Showing the first eight; more decompositions exist.
